Countries in the EU
The EU roster is a fixed 27-state list, which makes it one of the few prompts where the answer pool is closed — and the rarity spread inside it is enormous: four reflex powers, and a tail of small members most players never type.
Updated 2026-11-04 · rarity tags are our editorial guide (Obvious → Gem), calibrated against recorded playthroughs.

Traps & near-misses
- Norway and Switzerland are NOT EU members — the two most-typed invalid answers.
- The UK left the EU (Brexit, 2020) — no longer valid.
- Cyprus is geographically Asian but an EU member — valid either way.
How this helps in the dive
EU prompts reward knowing the small members. France and Germany are free points for everyone; Malta, Luxembourg and the Baltic trio are where your answer out-sinks the crowd. Exact membership matters: Norway and Switzerland are the classic invalid near-misses.
